CAR-JDOOR.

SPECIFICATION forming part of Letters Patent N. 683,565, dated october 1, 1'91.

serial No. 60,226. (No moda.)

To @ZZ whom t may concern:

Be it known that we, WILLIAM MARTINEK and HENRY J.HULsKER,citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have in- Vented certain new and useful Improvements in Car-Doors; and we do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to -make and use the same.

This invention relates to doors, and particularly to that class known as sliding doors, for use on freight-cars.

The object of the invention is to produce a door which is slidable longitudinally of the car-body and in combination therewith novel mechanism for moving the door into the dooropening flush with the car sides.

Furthermore, the object of the invention is to produce a novel form of latch for lretaining the mechanism in the position to which it is adjusted when the door is in place to close the opening.

Furthermore, the object of the invention is i to provide novel means for directing the rear edge of the door in alinement with the car side and mechanism for swinging the front edge into the door-opening and retaining it in said position.

Finally, the object of the invention is to produce a door and its operating mechanism which will possess advantages in points of efficiency, simplicity, and durability, proving atthe same time comparatively inexpensive.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this speciticatiomwherein like characters denote corresponding parts in the several views, and in which- Figure l is a perspective view of afragment of a freight-car body with the invention applied. Fig. 2 is a vertical sectional view in front of the operating-bar. Fig. 3 is a horizontal sectional view through the latch. Fig. 4 is a sectional view showing the rear hanger in detail. Fig. 5 is a view in elevation of the latch. Fig. 6 is a horizontal sectional view Q showing the latch, on an enlarged scale. Fig.

7 is a vertical section on line 7 7 of Fig. 5. Fig. 8 is a sectionalview on line S 8 of Fig. l. Fig. 9 is a plan View of the track. Fig.

10 is a sectional view on the line 5c ol Fig. l with the operating-bar out of position for locking the door. i y

In the drawings, 1 indicates the track; which extends parallel to the car-body for a portion of its length and then approaches the said body. The vcardoor is supported by hangers 2 and 3, the latter of which travels over the curved portion of the track and carries the rear edge of the door into the door= opening in line with the side of the car. A guide-plate 4 is secured along the edge of the door-opening to the post 4a, and as the rear edge of the door contacts with it said door is directed to its proper position. The rear edge of the door is beveled and sheathed by the metallic strip 5. The post 4: is recessed and beveled at et to correspond With the bevel of the door with which it interlocks. The hanger 2 has pivoted to its lower end the upper end 6 of an operating-bar 28, said end being bent at right angles to the bar. The lower end 29 of the bar extends at right angles to the bodyT in an opposite direction to that of the upper end and is provided with a cross-pin 9, adapted to swing into the recess 10 in the car side back of the plate 11, said plate having lugs, back of which the cross-pin lies, to prevent the outward movement of the lower end of the door when the mechanism is set to retain the door closed. The lower end of the operatingbar is recessed at 30 in order to pass the'guidebracket 3l on the side of the car when the operating-bar is turned to the position shown in Fig. 10, when the door is free to travel. The operating-bar is partially rotated in any suitable bearings 12, secured to the car-door, and a collar is fastened to the operating-bar and an arm 1 3 is pivoted to the collar for turning the operating-bar in its bearings.

When it is desired to open the door, the operating-bar is turned and the angular end is withdrawn from engagement with the plate.' At the same time the upper end is turned on the hanger and the forward end of the door is swung out of line with the side of the car and is free to move as the rollers 14 of the hangers travel on the track. The arm 13 also acts as a hasp,as it has a slot 16 for the reception of a staple 17, and the arm is retained in the staple by a pin 1S. The outer end of the arm has secured thereto the mem- IOO bers 19 'and 2O of a latch, which normally stand apart. A plate 21 is set in the car side and has an opening 22, into which the members of the latch are inserted when pressed together. When the latch members are in place, they are released, and, being free to resume their normally-separated position, spring back under the lugs 23 of the plate and can be released only by being pressed together out of engagement with the lugs.

The lower edge of the door is beveled, -as shown at 24, andra plate 25 is secured on the outer surface and depends below the edge of the door.

A wear-plate 26 and a buEer-plate 27 are secured on the outer surface of the car, the former to protect theside of the car and the latter to limit the movement of the door in one direction.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In a sliding door, a track having a curve at its rear end, hangers having wheels traveling on the tracks, an operating-rod having an angular end pivoted to the front hanger and an oppositely-disposed lower end, and adapted to lie in a recess in the car-body, when the door is closed, a cross-pin on the lower end, a plate having lugs engaged by the cross-pin and means for manipulating the operating-rod.

2. In a sliding door, a track curved inwardly at its rear end, hangers having wheels engaged by the track, a door having a beveled rear end, a guide projecting from the rear of the door-opening to engage and guide the door, an operating-rod on the outer surface of the door in the front, said operatingrod being pivoted to the lower end of the front hangers and having an angular lower end adapted to enter a recess in the ear-body, an arm secured to the operating-bar and a springlatch on the end of the arm substantially as described.

3. In aslidin g door, a track having a curved rear end, hangers having wheels traveling on the track,an operating-rod having oppositelybent ends, the upper end being pivoted to the front hanger and the lower end adapted to engage a plate in the car-body for holding the door closed a hasp-like arm secured to the operating-rod and a spring-latch on the end ofthe arm substantially as described.

4. In a sliding door, a track having a curved rear end hangers having Wheels traveling on the track,'an operating-rod having oppositelybent ends, the upper end being pivoted to the front hanger and the lower end adapted to engage a plate in the car-body for holding the door closed, a hasp-like arm secured to the operating-rod and a spring-latch comprising two diverging members adapted to be pressed together, and a plate on the side of the carbody having a central opening and lugs under which the members are expanded when released by the operator, substantially as described.

5. In a car-door, a door having a beveled rear edge, a door-post having a beveled surface to interlock with the rear surface of the door, a guide-bracket for the door, an operating-bar pivoted to the door for locking the same, said bar extending below the base of the door and engaging a locking-plate in the car side, and being so shaped as to pass said bracket, hangers for the door, a track for the hangers and means for turning the operatingbar substantially as described.

In testimony whereof we aiix our signatures in presence of two witnesses.
